A recent study has tried to establish a relation between Global warming and sea-level rise and has concluded that there is a link. The study considered data of the past 150 years and established that the sea absorbs most of the greenhouse gas emissions. These go to heat up the water and lead to sea-level rise with a corresponding increase in the intensity of climatic disorders like hurricanes and typhoons.

The Guardian reports only a small percentage of the greenhouse gas emissions heat up the air, land and ice caps. The National Academy of Sciences has published details of the study. It relied on data of the surface temperature of the ocean since 1871 and correlated that with computer models of ocean circulation.

In the opinion of scientists, analysis of past data helps to predict the future impact of climate change.

Global warming is a danger

There is a positive link between global warming, climate change, and sea-level rise. It must be realized that a rise in sea-level is one of the most dangerous long-term impacts of climate change. It is a threat to people who live in coastal areas because they have to face the ravages of nature in the form of hurricanes and typhoons that bring with them the loss of lives, and properties with the destruction of infrastructure. Rebuilding these are not only time consuming but also costly. Of course, a rise in sea levels happens due to the melting of glaciers but the effects of the physical expansion of water as it gets warmer is a major factor.

Prof Laure Zanna, at the University of Oxford, was the leader of the new research. In her words – “we are putting a lot of excess energy into the climate system and a lot of that ends up in the ocean.” The amount of total heat absorbed by the oceans over the past 150 years is mindboggling.

It could be the equivalent of nearly “1,000 times the annual energy use of the entire global population.” This study could help predict the future sea-level rise for different regions.

It is necessary to address global warming

According to National Geographic, the 2015 Paris accord on climate change activated a trigger.

It set the trend for the world to address various issues related to the implications of global warming and treat them with the seriousness they deserve. The main objective is to arrest the emissions of heat-trapping gases like carbon dioxide that come from burning fossil fuels and embrace Renewable Energy. Other actions could be to restore the lost green cover and plant mangroves on the coast to act as a buffer to floods. There is an awareness about the problems and some possible solutions. It is necessary to implement these in order to save the world.
